 Anil,
       Yes, there is DEFINITELY a downside.  If the pump is energized every 
moment the ignition is on, then it can flood the engine if the carbs cannot 
hold the pump pressure when the engine is stopped.  Imagine driving along, coming 
to a stop and having the engine stall.  With the ignition on, the pump keeps 
trying to pump gas into the carbs.  That's why most people using electric fuel 
pumps wire them through an aftermarket oil pressure switch which will shut 
off the pump once oil pressure disappears (stalled engine).  The wiring also 
uses a bypass so that energizing the starter even without oil pressure will turn 
on the pump to fill the carbs while the engine is cranking.  In addition to 
these, I also use an impact switch (like most late model Fords use) which will 
shut off the pump if the car is in an accident but still has the engine running 
and the ignition switch on.  All these items are really necessary especially 
in New Jersey since our gasoline is so much more flammable than that in other 
states.  That must be why we are NOT allowed to pump our own gas but must only 
permit a "trained technician" to do it.(:-)
       If you want to be able to prime the carbs BEFORE you try starting, you 
can install a priming PUSHBUTTON (NOT a switch) on the dash that energizes 
the pump directly while bypassing the above safeguards.
       Better safe than sorry.
